Also asked, what is meant by camera calibration?
Geometric camera calibration, also referred to as camera resectioning, estimates the parameters of a lens and image sensor of an image or video camera. You can use these parameters to correct for lens distortion, measure the size of an object in world units, or determine the location of the camera in the scene.
One may also ask, what is camera calibration in Lightroom? As the name suggests it’s focused originally around calibrating your raw converter to ensure your images look within the software as they do out of the camera. Adobe offers a basic default setting called ‘Adobe Standard’ which can look different, and thus offers profile options to emulate camera settings.
In this way, why is camera calibration important?
High resolution means that the camera should be able to decipher the smallest possible change. So, the camera should be calibrated to achieve higher accuracy and low distortion which helps in achieving the higher accurate representation of the real world in the captured images.
How do you calibrate a lens?
To start calibrating your lenses, set up your camera on a tripod or a flat surface. A table is fine. Ensure both the camera and ruler are level, exactly perpendicular and at the same height. Then, place the focus pyramid on a level surface about six feet from your lens front.
